Which drainage instrument is most effective at clearing venous coagula?

A girl of 50.0-kg skating at 10 m/s crashes into another girl of mass 35.0-kg moving in the same direction at 8.0 m/s.  Assuming the impact lasts 0.15 s, after which they move together, what is the average force (in units of N) that the 50.0-kg girl exerts on the 35.0-kg girl during the crash?

A Lazy Susan (turning tabletop) has radius 0.750 m.  An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s.  What is the value of the apple’s tangential acceleration at 3.00 second in m/s2? Enter units as “m/s^2”
